(c1. 20-4) The invention has relation to building material 9, intermediately of the widths of said faces and for log houses, having for an object to provide a of dimensions one half inch by one half inch use for lodge pole timber which is of little value approximately in cross section, the grooves of for square timber owing to its small size. Another adjacent half logs registering.

Another obis not adapted for use as building material as it ject is to provide an insulation means against will split or chock open to admit moisture, the the entrance of water between the logs and also lodge pole timber used herein is split or sawed 10 against the entrance of air between the logs. lengthwise centrally thereof and the half logs Another object is to provide logs for use with such squared on top and bottom as stated, the finished insulation means, said logs reversible end for end dimensions of each half log being about four by to match up for thickness of the logs.
